Title: Single handle locomotive controller
Inventor: ROOT KEVIN B
IPC: B60T13/66
Filed: 1991-10-23
Granted: 1999-06-01
Abstract: A locomotive control system having a single handle movable between a maximum propulsion position, through diminishing propulsion positions, through a release/idle position, through increasing braking positions, through a full service brake position to an emergency brake position.  The control system receives position signals from the handle and generates propulsion, dynamic braking and fluid braking control signals as a function of the position signals.  For any braking position of the handle, the control system first applies or removes dynamic braking and then provides fluid braking depending upon the position of the handle, the type of train brakes and whether the dynamic braking has maximized or is zero.
